How Window Shutters Give You Control Over Room Temperature Closed shutters are the next best barrier against the extreme temperature and wind in Houston, coming right after windows. Window treatments such as blinds, draperies, and shades block most of the temperature from the outdoors, but not all. And, where your window treatment’s quality means the difference between a cozy seat by the window and one that’s not, Polywood® shutters are your best choice. Polywood shutters are built from a synthetic polymer. Polywood shutters insulate up to 70% better than a comparable traditional wood shutter. As a matter of fact, the Polywood Shutter Insulating System blocks up to 30 degrees of airflow and diminishes heat transfer by 45.96%. This results in energy savings for your house – and full room temperature control. The heating and cooling system in your residence won’t have to work so hard now that you have reduced the impact from the weather outside. If you want to feel some of the light and be more exposed to the outside temperature, just slant the louvers open and adjust them to a preferred position. You can get even more window treatment temperature control by closing your shutters properly. How to Close Your Shutters for Maximum Temperature Control Two parts of your shutters should be closed to seal off external temperature: the panels and the louvers. To properly close your Polywood shutter panels, swing them toward the window. As you push the panels into the shutter frame, check that the pieces of weatherstripping interlock along the vertical ends of your shutters. To properly close your louvers, push the tilt rod toward the louvers, making sure the top of the tilt rod will fit into the "mouse hole," which is above the top louver. The best way to do that is to run your hand up the tilt rod, and push in as you go up. This is particularly true for taller shutters – sometimes a small push at the bottom of the tilt rod isn't enough and doesn’t close gaps at the top.
